To all whomit may concern: j Be it knownthat I, SAMUELW. MrLLEa, a

citizen of the United States, 'residing--at Philadelphia. in the county'ofJ-Philadelphia and Stateiof Pennsy1vania,'have invented a certain new Side-Dump Cars, of which the following is'a specification i f j The invention relates more particularly to 16 what are known, assteel side-discharge cars, an illustration of which .is found ingthe United States patent issued to William .0.

e invention consists in the construction forms of the partsillustrated in the accomf Epanyin'gdrawmgs. Insaid drawings, Figure 1 is a fractional view infelev ati'on of the side of the car near its end, a portion being broken out. Fig. 2 is fa vertical sectional. 'ew taken on a line a: w, Fig5 1,; Fig. 3 is a detail illustrating con- 6 ventionally the chain-gearing for operating the door. Fig. 4 illustrates fractionally in -'.plan.view the mechanism at the end of'the *car-: for operating the doors. Fig. 5 illustrates a side view of what'is shown in Fig. 4. 5'. Fig.6 illustrates conventionally, on a smaller scale, how the chains at-the end of the car are crossed to effect the simultaneous operation of, the doors at both sides of the car in the same direction. In the views, 1 designates the vertical SlClB proper of the car-body. Along the lower edgeofeach side of the said vertical portion is secured an angle-bar 2, arranged w1th 1ts corner upward, so as. to form, in" conjunction with metal of the car, a longitudinal pocket or recess 2 in-the side of the car.

d useful Improvement in T he metal of the side of the car where the pocket is formed is shown to be bent from the point of inclinedly inward and downward, then vertically downward, and-then outward to form the cavity, the metal bein suitably stren thened by added bars, as s own, if desire or j angle-bar is secured in place it forms a down- 'W1thin each of thepockets 2 there is jourshaft3.

' Below the pocket the car-body generally is.

grooves 4; j r I I The character'5.designatesthe doors. The ends of the doors engage the grooves 4, so that they can be slid up and down in them.- Adjacent the grooves the doors are provided with ribs or projections 5 and connecting adjacent doors are bars 6, secured to the ribs 5. All the doors on the side of the carcan at each end of thecar where it does not adfor the pur oseof e ualizing the pull of the operating-c ains, as ereinafter explained.

l In the lower ends of the spaces between the doorways is mounted a small grooved idler idler S. On the shaft is secured achain idler 7 and over the guiding-idler 8 is passedan necessary, 'Itwill be noted that when thei join another door is provided with a pin 6 l driving wheel-9.

The end of the door .90 l ,7 and between suitable hearings in the pocket. i 2*. below the shaft 3 is mounted a guidingnected to the several pins 6 and also to pins i 6*, so that upon rotatingtheshaft 3 in the i proper direction the doors at the side ofthe car can all be raised or loweredsimultane ously. The provisionof the pin 6..is de 5 signed to insure an equal draft on' both ends f of the end door and prevents it from tilting the grooves and'sticking therein.

. 11 designates .an operating-shaft at the Z'end of the can. This shaft canbe provided 5 at itsouter end with a radially-socketed hub. L 11, into which a hand-operated bar can be" inserted for turning the shaft; .The inner ;-end of the shaft 11 is provided with'a twin chain-driving wheel-11 ,over which endless i-chains 12 and 1 2 are run to appropriate wheels on shafts 3. To effect the simultaneons raising or lowering of the doo atppposite sides of the car, one of the char s (as at 12*, Fig. 6) from the "twin wheel can be crossed in accordance with. well-kridwn prac tice. As shown, an ordinary pawl-and atchet device for latching the'shaft 11, and therefore the doorsas they are raised. to discharge the load, can be provided. I

The car can of course be constructed mainly of wood; but in practice it is best constructed of steel.
